Title: Expansible and retractible tubular means
Inventor: JARVIS DUGLAN
IPC: F16L37/06
Filed: 1989-04-13
Abstract: An expansible and retractible means comprises a length of resilient, tubular, fluid impervious material 10 closed at at least one end, said tubular material over at least a part of its length being formed to a required configuration with parts of the length 9 in side-by-side relationship, and there being a means 5 of causing an expansion or contraction of the tubular material over at least the said part of its length of required configuration. Thus with the tubular length fluid filled, a part of its length can be contracted to cause the fluid to expand the other part of the length which may be formed as a helical winding or as a flat concertina. Equally the tubular length may be filled with an electrorheometric fluid to which an electric charge can be applied to convert the fluid to solid gel form, and when the heating effect on the fluid is such as to cause it and hence the tube to expand. The expansible and retractible means can be used as a connector for pipes and/or rods, can parody a muscle function, or respond like a tentacle, or can be used for assimilating a peristaltic action in a tube. <IMAGE>

Title: "Method and apparatus for rendering overlapping images on a graphics display device"
Inventor: CARRIE SUSAN E
IPC: G06T15/40
Filed: 1991-06-26
Abstract: A pixel buffer 110 separate from the frame buffer 108 is provided to store selected pixel information, including XYZ values, sub-pixel coverage, and a color value for a graphic object. The frame buffer 108 stores pixel information for each pixel on the screen, including sub-pixel coverage. During the rendering process, the pixel information for each graphic object is computed and stored in the frame buffer 108. However, as subsequent pixel information for the same XY pixel locations are computed, it may be impossible to combine the two separate sets of pixel information into a single set of pixel information while maintaining the pixel information required to combine the single set of pixel information with subsequent pixel information to be rendered to the same XY location. To maintain the pixel information needed, the first set of pixel information is stored in the frame buffer 108 and the second set of pixel information is stored in the pixel buffer 110. The second set of pixel information stored in the pixel buffer is then subsequently reprocessed. The pixel buffer permits the processing of selected pixel information to be postponed until additional pixel information is available which may simplify the processing of the pixels shared in the pixel buffer. In addition, this pixel information stored in the pixel buffer may be made available to a general purpose processor which can perform selective complex computations. Thus to display a plurality of possibly overlapping objects, each pixel is divided into sub-pixels and the final content of each sub-pixel updatedly analysed, as each object is considered in turn, as to the object(s) covering that sub-pixel, by a series of 3 updating comparisons and loadings of the frame buffer to store the image for display and the pixel buffer to store the hidden portions. <IMAGE>
